COMBINED WATER-=HEATER AND SHOWER-BATH.

SPECIFICATION forming part of Letters Patent No. 489,660, dated January10, 1893. Application filed July 14, 1892. Serial No. 440,068. (Nomodel.)

To aZZ whom it may concern: wall and head being formed by the conical Beit known that 1, JOHN PELLOW, a citizen extension A and the annular headD. Openof the United States, residing at Grand Raping in to the top ofthis chamber, is a pipe J ids, in the county of Kent and State ofMichihaving no valve or other means of closing the gan, have inventedcertain new and useful same, which pipe extends upward and to anyImprovements in a Combined Water-Heater convenient point where itterminates in a and Shower-Bath; and I do hereby declare sprinkler K,for the purpose of a shower bath; the following to be a full, clear, andexact deand from the lower part of said chamber exscription of theinvention, such as will entends a pipe G provided with a valve G, 60 1oable others skilled in the art to which it apwhich extends to anyconvenient point to dispertains to make and use the same. charge hotwater from said chamber.

My invention relates to improvements in a E is a pipe connected to anyconvenient combined water heater and shower bath, and water reservoir,or hydrant, which pipe is its object is to provide the same with certainprovided with a valve E, and extending 65 new and useful features,hereinafter more through the casing Aabove the burners H, is

fully described and particularly pointed out provided with a cross E, towhich are conin the claims, reference being had to the acnected theconical spiral pipe coils F F which companying drawings in which extendupward within the described tubular Figure 1 is a vertical section of adevice sections and cups, and passing vertically 7o embodying myinvention on the line 11 of through the upper cup B, are closed at theirFigs. 2 and 3. Fig. 2 a horizontal section of upper ends and perforatedwith a number of the same on the line 22 of Fig. 1; and, Fig. openings Fon their sides adjacent to the up- 3 the same on the line 3-3 of Fig. 1.per tubular section 0". Extending from the A represents a cylindricalcasing, within supply pipe E to the shower bath pipe J and 75 which arelocated burners H for gas, gasoline, connecting the same is a pipe Lprovided or other fuel, which burners are supplied with a valve L. Theburners H serve to heat through the pipe 1. Attached to the upper thecoils F F, tubular sections 0 O 'O 0 part of the base A, is a truncatedconical exand the cups B B B B ,which collectively tension A terminatingat its upper end in an present a large and efficient heating surface, 80o annular head D, said head surrounding and water being turned on byopening the valve attached to the smallest tubular section 0, E, willflow through the pipe E and coils F which section extends above saidhead, to F and escaping at the openings F is sprayed connect with asmoke pipe and also extends upon the section 0, and running downwardbelow the same a short distance, terminating on the outer surface of thesame, accumu- 85 5 in an annular cup 13 surrounding its base, lates inthe cup B, whence it over flows and to the outer rim of which cup isattached a passing downward over the successive seelarger tubularsection 0, which also has attions G O O and through the cups B andtached another larger annular cup B, to the B finally accummlates in thelower cup B, outer rim of which is attached the upper end whence itpasses off at the pipe G when the 0 40 of another still larger tubularsection 0, valve G is open. These cups B B B' which has another annularcup B at the botare found to be very effective for strengthentom, towhich is attached the upper end of ing the structure against pressure ofwater another tubular section 0, which also has an from without and alsofor deflecting and annular cup at the bottom, the outer rim of breakingup the upward current of heated 95 which is attached to the base A nearits upair and gases, and also increasing the heatper end, thus making aseries of upwardly ing surface of the device. decreasing tubularsections C O C O" in se- By closing the valve G the water will fill riesone above the other, connected at their the device and then overflow atthe pipe J, adjacent ends by upwardly open annular escapingin aspray ofhotwater at the sprink- 10c cups B B B B which form the inner walls lerK; should said water he too hot, a portion and bottom of a waterchamber, the outer of cold water may be added by opening the valve L,more or less, the resistance due to the convolutions of the coils F andthe narrowness of the openings F, causing a portion of the water to takethe free course through the pipe L, according as the valve L is openedmore or less. In case both valve G and E are inadvertently closed noover pressure can be produced to explode the device, as all excess ofpressure at once escapes through the pipe J and sprinkler K. Nor is itpossible to put full hydrant pressure upon the device, as all excess ofpressure over what is necessary to drive the water over, escapes throughsaid pipe J and sprinkler K, which should be large enough to pass freelyall the water that can be admitted through the valve E.

The structure can thus be made thin and light, which facilitates rapidheating, and is also cheaper and at the same time is insured against anyaccident from over pressure, which in case of a device that can bewholly closed and steam generated in the same, can be exploded,regardless of its strength, and is therefore very dangerous.

What I claim is;-

1. In a water heater, the combination with the tubular sections ofdiiferent diameters, cups at the ends of said sections, and the easingsurrounding said sections and cups, of the spiral coils extendingupwardly through the lower of said sections and having their upper endslocated adjacent to the exterior of the upper of said sections andformed with lateral openings, substantially as shown and described.

2. In a water heater, a series of diminishing tubular sections connectedby annular cups, and a truncated conical casing connected to one of saidcups at its base, and to one of said tubular sections at its oppositeend, and a conical spiral coil within said sections and cups connectedto a water supply at one end, and passing through the upper cup at theopposite end, and having a series of openings in the side adjacent toone of said tubular sections, substantially as described.

3. In a water heater, a cylindrical casing, having burners or otherheating devices within the same, a tubular conical extension attached tosaid base, a series of upwardly diminishing tubular sections connectedby upwardly open annular cups within said conical extension, a headconnecting said extension to the upper tubular section, a transversepipe in said casing above said heaters, conical spiral coils connectedto said pipe and extending upward within said tubular section and cups,said coils passing through the upper cup and having lateral openings inthe side adjacent to the upper tubular section, and a discharge pipeattached to the lower annular cup, substantially as described.

4. The combination, in a combined water heater and shower bath, of acasing, tubular sections of different diameters located in said casing,cups at the ends of said sections, the burners, spiral coils extendingupward within said tubular sections and having their upper ends locatedadjacent to the exterior surface of the uppermost section and formedwith lateral openings, a permanently-open pipe, J, extending from theupper end of said casing and provided at its outer end with a sprinkler,a valved pipe G extending from the lower cup, a valved pipe E connectedwith the lower ends of said coils, and a valved pipe L connecting saidpipes J and E.

5. A combined water heater and shower bath, consisting of a series ofupwardly diminishing tubular sections, annular cups connecting theadjacent ends of the same, a truncated conical outer shell connected tothe outer rim of the lower cup at its base and to the upper tubularsection at its smaller end, burners in said casing conical spiral coilswithin saidsections and cups, said spiral coils extending through theuppermost cup and having series of openings in their sides adjacent tothe uppermost tubular section, a permanently-open pipe, J, extendingfrom the upper end of said casing and provided at its outer end with asprinkler, a valved pipe G extending from the lower cup, a valved pipe Econnected with the lower ends of said coils, and a valved pipe Lconnecting said pipes J and E.

In testimony whereof I affix my signature in presence of two witnesses.
